The GeoPac® Dewatering Tubes and Bags are geotextile equipment used for removing, dewatering, and reducing the number of different types of sludge materials. The dewatered sludge flows through the tube placed on the ground or in your sludge boxes, with the accumulated sludge becoming a filtering system that leads to cleaner effluent.
Many of our customers use our dewatering bags for dredging agricultural waste, beach restoration, industrial sludge removal, construction dewatering, pulp and paper waste removal, marine dredging, and wastewater sludge removal. The geotextile tube uses internal pressure to dewater instead of gravity.Get a Quote

PacTec offers several sizes and variations of geotextile dewatering bags and tubes, from small 5’ sludge bags up to 60’x200’ multi-spout tubes (and everything in between). We also offer a tube designed to fit perfectly in a roll off container for ease of use.
PacTec offers dewatering tubes in several materials with varying micron ratings to meet your needs. These range from 50 micron to 260 micron. If you are unsure which option is best, contact a member of our team and we will gladly assist you.
PacTec’s smaller geotextile dewatering tubes typically only have one fill spout and larger sizes have multiple spouts. However, if you have certain specifications or requests, PacTec can certainly accommodate those for you. Just reach out to one of our team members for assistance
No, PacTec only provides the dewatering product and does not offer pumping service. However, we do have experts on staff with many years of experience to offer recommendations and answer any questions you may have during the process.
You bet! PacTec only uses high-tenacity threads to construct our dewatering products, designed specifically to withstand the pumping pressure you will be using. Our team of experts can provide recommended pressure setting for your project to ensure success.
Depending on the material being pumped into the dewatering tubes, blinding can occur. If this happens on your project, we recommend moving the hose occasionally to open areas within the tube. We can provide more detailed information on request.
PacTec has a dewatering solution to meet your needs and space constraints. For large open areas, larger tubes may be an ideal product for you. For those with limited space or access, smaller dewatering bags or roll off container dewatering bags may be more ideal. We can help you decide the best methods and products based on your dewatering volume and project space. Reach out to our team for assistance if needed and we will be happy to help.
Dewatering boxes are typically expensive to rent and difficult to obtain but are often a very effective method of dewatering. However, dewatering tubes may be a better option if you have a large volume to dewater or need to dewater faster, as tubes utilize gravity AND pressure to dewater faster than filters. Here is a helpful guide for determining if tubes are the right option for you.
Geotextile tubes can indeed be stacked if space allows. Many of our customers have had great success with this.
How you deal with the water extruded from your dewatering process is determined by several factors, including how clean it is, if it contains contaminants, if the site has certain requirements, etc. Some users capture the water to be utilized in other processes or send it through filtration processes to make it potable. Others allow it back into the environment.
This is where the true benefits of geotextile dewatering bags shine, as the solids are already contained within a tube/bag for easy disposal. Plus, the disposal will cost less as it weighs less. Small tubes can be disposed of as is, where larger tubes are often cut open and the solids excavated out because of their weight and solids volume.
